Adempas (riociguat), an approved therapy for adults with pulmonary arterial hypertension (PAH), was well-tolerated in children and adolescents with PAH, with no new safety signals, according to data from PATENT-CHILD — the first pediatric trial of the therapy. The medication, used off-label for pediatric PAH patients with doses tailored…

A gene therapy designed to provide a protein implicated in heart function improvement was found to lessen pulmonary blood vessel remodeling and reduce lung blood pressure in a preclinical study of pulmonary arterial hypertension (PAH). The study, “Apela gene therapy alleviates pulmonary hypertension in rats,” was published in…

Pulnovo Medical reported that it “successfully concluded” a first meeting with the U.S. Food and Drug Administration (FDA) regarding the design of a pivotal clinical trial of its pulmonary artery denervation (PADN) device in people with pulmonary arterial hypertension (PAH). PADN aims to lower pulmonary artery pressure by…

An under-the-skin infusion of a protein called netrin-1 — originally found to regulate nervous system development — shows promise for lessening pulmonary hypertension (PH), a mouse study suggests. Additionally, the scientists found that three small peptides derived from netrin-1 also are a potential therapy for easing PH. The…

Aerovate Therapeutics‘ AV-101, an inhaled formulation of imatinib for treating pulmonary arterial hypertension (PAH), was well tolerated in healthy adult volunteers enrolled in a Phase 1 trial. Study data also indicate AV-101, which delivers the medication directly to the lungs, reduced its systemic (whole body) exposure. This is…

The levels of blood-circulating inflammatory molecules differ between men and women with pulmonary arterial hypertension (PAH) and correlate with disease severity, a study suggests. Notably, the levels of two proteins — called IL-6 and MIP-1alpha — were predictors of poorer survival statistics. These findings suggest that patient stratification may…

A first patient in the U.S. has been dosed in a Phase 2b trial testing Respira Therapeutics‘ inhaled medicine-device combination product, called RT234, as a therapy for pulmonary arterial hypertension (PAH). The trial (NCT04266197), dubbed VIPAH-PRN, for Vardenafil Inhaled for Pulmonary Arterial Hypertension – PRN, will test…

A bilateral or double lung transplant can rescue heart function in children and adolescents with pulmonary hypertension (PH), a U.S. single-center study reports. Specifically, a transplant was found to effectively normalize right ventricular (RV) function of the heart in PH patients up to age 21. Additionally, RV dysfunction prior to…

Levels of fractional exhaled nitric oxide (FeNO) — a measure of how much nitric oxide a person exhales — may help diagnose pulmonary hypertension in patients with acute exacerbation of chronic obstructive pulmonary disease (COPD), a Chinese study suggests. Nitric oxide, called NO, is a vasodilator that helps…

Claritas Pharmaceuticals now has exclusive worldwide rights to develop and market R-107 — a liquid form of nitric oxide — for the treatment of pulmonary diseases such as pulmonary arterial hypertension (PAH), acute respiratory distress syndrome (ARDS), and persistent pulmonary hypertension of the newborn (PPHN). In its announcement…

Elevated levels of three blood proteins — AMBP, LPL and glyoxalase I — may help identify and distinguish people with pulmonary hypertension linked to heart failure with preserved ejection fraction, called HFpEF-PH, from those with pulmonary arterial hypertension or PAH, a study suggests. Differentiating between the two is key,…

OxiWear has raised $1.25 million in funding to support the final steps in the commercialization of its ear-wearable device, designed to continuously monitor blood oxygen levels in people with pulmonary hypertension (PH). The funding round, initially with a target of $750,000, was well “oversubscribed,” the company reported in…
